摘　　要：在湖南攸县设置了反映湿地松人工林造林各主要技术环节的试验林体系,以研究不同造林技术措施对湿地松幼林生长的影响。经对试验林固定样地进行连续7年定期、定位观测及统计分析表明:在湿地松人工造林的各项主要技术措施中,立地选择、良种选择和造林密度是影响幼林生长的最重要因素,幼林抚育对湿地松幼林生长有较明显影响,而整地方式与规格对幼林生长无明显影响。Different experiments designed to test different techniques for slash pine(Pinus elliotii Engelm)afforestation were carried out at You county,and analyzed the affects of different afforestation measures on the growth of juvenile trees.The results from the seven-years successively,regularly and locally observation,statistic and analysis showed that choice of site,high quality seeds and density are the important factors which affected the growth of young trees,during the afforestation.The tending of juvenile stand affected the growth obviously,and the methods of ground preparation resulted in no effect on the growth.
